The problem
For most SMBs between 11 and 100 employees, 1099 reporting is a January problem solved with a December panic. Vendors get onboarded by whoever needed the work done, payments flow through bookkeeping software that was never designed as a tax system of record, and the W-9 lives in someone's inbox or, worse, was never requested. By the time the controller pulls a vendor list for the tax year, half the records are missing a TIN, a quarter have stale addresses, and a handful are duplicated under three slightly different counterparty names from imported bank transactions.
The IRS does not care about your bookkeeping shortcuts. The $600 reporting threshold for 1099-NEC is unforgiving, and exceeding it without a valid Form W-9 on file exposes the payer to backup withholding obligations, $310-per-form penalties under IRC Section 6721, and intentional disregard penalties that scale with revenue. Add in state-level 1099 filing requirements, which diverge sharply across the combined federal/state filing program and direct-file states, and the edge cases multiply.
The chase emails compound the chaos. Controllers send the same "we need your W-9 before year-end" message to twenty vendors, track replies in a spreadsheet, manually transcribe TINs from PDFs, and hope nobody fat-fingers a digit. ATCS replaces that workflow with a structured vendor system that knows which payments count, which TINs are missing, and which W-9s expired.
How it works
Continuous 1099 eligibility tracking
ATCS evaluates every vendor against the current IRS reporting threshold on a rolling basis, not once per January. Each vendor record is tagged with a tax year, a running payment total, a 1099-eligible flag, and the form type that applies (NEC for nonemployee compensation, MISC for rent, royalties, and other categories). The moment a vendor crosses the $600 threshold, they appear on the 1099-eligible roster. If their TIN is missing, they appear on the missing-TIN dashboard the same day, giving you ten months of runway instead of ten days.
Tokenized W-9 capture
Rather than emailing PDFs and manually transcribing returned forms, ATCS generates a tokenized W-9 self-submit link for each vendor. Each token is single-use, scoped to one vendor record, and expires on a configurable schedule. The vendor completes the form in a browser, the data writes directly to the encrypted vendor record, and the controller is notified. No email attachments, no transcription errors, no W-9s sitting in a shared inbox waiting for someone to file them.
Encrypted vendor records
Vendor records hold the TIN, legal name, DBA, mailing address, contact information, and the original W-9 submission metadata. TINs are encrypted at rest, access is logged, and the vendor merge tool resolves the duplicate-vendor problem that almost every SMB inherits from migrating bookkeeping platforms. Transaction-level matching reconciles counterparty names from imported payment data against canonical vendor records, so "ACME LLC," "Acme, LLC," and "ACME Limited Liability Co" stop being three vendors with three partial TINs.
File-ready output
When you are ready to file, ATCS produces a CSV export of every 1099-eligible vendor with TIN, legal name, address, payment total, and form type, structured for upload to the IRS IRIS portal or any third-party filing service your firm already uses. Printable 1099-NEC Copy B forms are generated for vendor distribution, formatted to align with pre-printed IRS stock or to print directly on plain paper where permitted. Your CPA gets a clean handoff. Your vendors get their copy on time.

FAQ
When is the 1099-NEC deadline?
Form 1099-NEC must be furnished to recipients and filed with the IRS by January 31. There is no automatic 30-day extension for 1099-NEC, unlike some other information returns, so the January date is effectively hard.
What is the $600 threshold?
The IRS requires a 1099-NEC for any nonemployee paid $600 or more in aggregate during the tax year for services performed in the course of your trade or business. Aggregate means total payments across the year, not per-invoice. ATCS tracks the running total per vendor per tax year and flags eligibility automatically.
What about backup withholding for non-responsive vendors?
If a vendor fails to provide a TIN on a Form W-9, the payer is generally required to withhold 24 percent of payments as backup withholding under IRC Section 3406 and remit it with Form 945. ATCS surfaces non-responsive vendors on the missing-TIN dashboard so you can pause payments or initiate withholding before the obligation accrues.
What is the difference between 1099-NEC and 1099-MISC?
1099-NEC reports nonemployee compensation, the most common category for independent contractors and service providers. 1099-MISC covers rents, royalties, prizes, medical and healthcare payments, attorney gross proceeds, and other miscellaneous categories. ATCS categorizes payments to the correct form at the transaction level.
Does ATCS file the forms or just prepare them?
ATCS prepares file-ready output. The CSV export is structured for upload to the IRS IRIS portal or to a third-party filing service. Printable Copy B forms are generated for vendor distribution. ATCS does not transmit forms to the IRS on your behalf, which keeps your firm in control of the filing relationship and the signed authorization.
